(a) High MAF (MAF > 0.25) topology. (b) Low MAF (MAF < 0.25) topology. Nodes exhibiting bootstrap support levels of at least
50% or 90% are indicated by gray dots and black dots, respectively. Bootstrap support
and branch length differ between the topologies, but the American and Asian parasites
form congruent clades.

(a) Plot of the likelihood of the genotyping data given that the samples derive from K
= 1-5 populations. (b) Plot of the posterior probability of population membership for each sample hybridized
to the array, assuming three underlying populations.
